A Molecular Dynamic Study on the Equation of State for Argon Fluid at Temperatures Near its Critical Point
In this paper, we have developed an empirical formula describing the equation of state of argon fluid using cluster expansion technique and commonly used force parameters. To test the reliability of the formula, we have further simulated the equation of state for argon at corresponding states employing molecular dynamic method. The comparisons have shown that the empirical formula gives much better prediction than that from the simple form equation of ideal gases and the inclusion of the third virial terms in expansions is prominently important.
